Faster, Smaller, and Simpler Model for Multiple Facial Attributes Transformation
IEEE Access, 2019Co-Authors: Jonathan Hans Soeseno, Wen-yin ChenAbstract:There are many existing Models that are capable of changing hair color or changing facial expressions. These Models are typically implemented as deep neural networks that require a large number of computations in order to perform the transformations. This is why it is challenging to deploy on a mobile platform. The usual setup requires an internet connection, where the processing can be done on a server. However, this limits the application's accessibility and diminishes the user experience for consumers with low internet bandwidth. In this paper, we develop a Model that can simultaneously transform multiple facial attributes with lower memory footprint and fewer number of computations, making it easier to be processed on a mobile phone. Moreover, our encoder-decoder design allows us to encode an image only once and transform multiple times, making it faster as compared to the previous methods where the whole image has to be processed repeatedly for every attribute transformation. We show in our experiments that our results are comparable to the state-of-the-art Models but with $4\times $ fewer parameters and $3\times $ faster execution time.

Modeling of long, thin elastic structures with periodic geometry
[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 1992Co-Authors: R.e. MillerAbstract:The author considers the problem of Modeling a class of elastic structures characterized by having one dimension large relative to the other two and being periodic along the length. Since a direct approach to Modeling such structures leads to intractable numerical difficulties, a Simpler Model is Modeled by a linearized elastic system on a 3-D domain which is not simply connected. By letting a small parameter (the width of the cross section) tend to zero, two uncoupled (1-D) equations having the same form as the usual Euler-Bernoulli beam equation but with periodic coefficients are obtained. By a second limiting process (letting the period tend to zero), equations with constant coefficients (the homogenized equations) are obtained. Numerical results comparing the eigenvalues of the first limit equation with those of the homogenized equation are presented.

Design and Implementation of a Plain Grid Monitoring and Information Service
Fifth IEEE International Symposium on Network Computing and Applications (NCA'06), 2006Co-Authors: Zhongliang Chen, Chunhao Feng, Zhi WangAbstract:Grid monitoring and information service is a key part of a grid system, and sometimes it may he the bottleneck when improving the performance of a system. Therefore the design and implementation of it should be as simple as possible. However, many of the present tools about grid monitoring and information service are too large and too difficult to configure and use, at the same time they may increase costs of the system. So we designed a Simpler Model after we've analyzed the requirements and Model of grid monitoring and information service, and implemented it. The paper presents the design principles of our grid monitoring and information service "PGMIS" and how we implemented it

Robust, reduced-order Modeling for state-space systems via parameter-dependent bounding functions
IEEE Transactions on Automatic Control, 1997Co-Authors: W.m. Haddad, V. KapilaAbstract:One of the most important problems in dynamic systems theory is to approximate a higher-order system Model with a low-order, relatively Simpler Model. However, the nominal high-order Model is never an exact representation of the true physical system. In this paper the problem of approximating an uncertain high-order system with constant real parameter uncertainty by a robust reduced-order Model is considered. A parameter-dependent quadratic bounding function is developed that bounds the effect of uncertain real parameters on the Model-reduction error. An auxiliary minimization problem is formulated that minimizes an upper bound for the Model-reduction error. The principal result is a necessary condition for solving the auxiliary minimization problem which effectively provides sufficient conditions for characterizing robust reduced-order Models.

a microeconomic theory of international tourism demand
Annals of Tourism Research, 1992Co-Authors: Clive MorleyAbstract:Abstract Current Models of tourism demand based in economic utility theory assume a two-stage decision process, with the choice of tour independent of the prior decision to travel or not. In this article, a more comprehensive Model is developed that incorporates the decision to travel or not and the time and budget allocations, as well as the choice of tour in one utility function with nontourism goods. The new Model allows changes in incomes and in the prices of nontourism goods and services to affect tourism behavior in ways that the standard and Simpler Model does not, with implications for improved empirical Model formulation.
